0.6222... is a recurring decimal at the digit '2'
let x = 0.62222....
multiply x by 10 ⇒ 10x = 6.2222.... [we multiply by 10 to leave the recurring digits after decimal point]
multiply x by 100 ⇒ 100x = 62.2222... [we multiply by 100 so that we can again leave the recurring digit after decimal point]
subtract 10x from 100x
100x - 10x = 62.2222... - 6.2222...
90x = 56
x = 56/90
x = 28/45

The table is a linear function. This means that all the points have a consistent slope. If two points had a different slope, it would be a nonlinear function.
Slope is rise over run. We are given the points (-3,0) and (-2,-5).

Answer:

Step-by-step explanation:
Given

Required
Express as 
We have:

Apply second law of indices

So, we have:


Add 15 and 12 then divided by 144
